The best fashion from Emmy-nominated shows

DOWNTON ABBEY
This riding outfit reflects Lady Mary’s life of leisure among England’s privileged horsy set. “There is something impossibly elegant about the old-style riding wear from that era,” says Harper’s Bazaar editor Avril Graham. “Combined with the ladies riding side saddle, it makes a strict look seem very sexy without showing an inch of skin.”

Before cocktail hour, the ladies of the manor would ditch their tweedy togs and slip into wispy evening wear: “They wore beautiful updos to show off the elegance around women’s necks,” says Graham. “And gloves in the evening . . . everyone dresses for dinner and makes that extra effort.”

Eldest Crawley daughter Lady Mary is clearly a chapeau-holic.

“Matching colors of hats and suits were de rigueur for daytime,” Graham says.

“Ladies would have appeared underdressed without a hat and gloves,” Graham adds.

ONCE UPON A TIME
Mary Margaret: The inspiration for this feathery white dress came from fabric the show’s costume designer Eduardo Castro found in Paris. “This was the very first costume I designed for the show,” he says.

It’s a super pretty look that translates seamlessly to the modern world, as seen in this angelic cloche hat and Nanette Lepore coat in winter white. “Everything for her is romantic, and there’s a sense of sensuality,” Castro says.

Regina: Fans constantly rave about the Evil Queen’s travel outfit, but it’s actually Castro’s least favorite look from the series. “I hated what [the] hair [department] did to it,” he says. “It turned her into a drag queen.”

Back in the present day, Regina rocks this cinched gray Hugo Boss dress, and a thin Celine belt completes the style.

THE GOOD WIFE
Alicia: “Last season with Alicia, she definitely had a nod to the ’40s working woman,” says Lawson, who turns to Michael Kors, Calvin Klein and Dior when dressing her. “Julianna takes a certain [French model runway] pose when she really loves an outfit.”

Diane: Known for her strong statement necklaces, law firm partner Diane (played by Christine Baranski) steals the show in this powerful purple Oscar de la Renta dress.

Kalinda: “She’s kind of a superhero in my mind,” Lawson says of the show’s sexy investigator. This DKNY jacket in tomato red, which Lawson picked up at Bloomingdale’s, was altered to fit the body of actress Archie Panjabi, who plays the role.

GIRLS
Shoshanna: Rogien focuses on pinks and light teals when pulling looks for Shoshanna, who’s ever the girly-girl. Here, she wears a glitzy Zara skirt and magenta blouse, also from Zara.

Jessa: Rogien found this ethereal wedding dress at West Village boutique Geminola — which is owned by actress Jemima Kirke’s mother. The bohemian, off-the-shoulder shift is a perfect fit with Jessa’s fly-by-the-seat-of-her-pants persona, as is the tousled, yet pulled together look.

Jessa’s look is tousled, yet pulled together.

Marnie: “Here, she glammed up in a way that didn’t make sense for a Bushwick party at all, more like a bat mitzvah or a cocktail party on the Upper West Side,” says Rogien. “We found this great dress by Tibi, and the color was brilliant.”

Hannah: Her thrift-shop aesthetic gets some polish with this floral Theory frock. “We had no place to use this on our show until I got the script for the final episode, and I think it was the prettiest she looked all season,” says Rogien.

BOARDWALK EMPIRE
Lucy: Bad girl Lucy Danziger keeps it sleek and sexy with many of her looks, wearing luxurious silks and beaded bodices. “It’s all about the elegance and opulence of time gone by,” says stylist Phillip Bloch.

Nucky: “All the fabrics are of the period,” says “Boardwalk Empire” costume designer John Dunn. “We never use contemporary fabrics with men’s suits or women’s dresses.” Last season, Nucky Thompson ditched the flash for a more low-key look in windowpane plaid.
